Abstract

A quick release and attachment assembly for the operating tools (10) for earthmoving or excavating machines has an attachment head (23) pivotally mounted on the boom (24) of the machine.
A locating head is fixed to, or formed integrally with, an operating tool (10) and has a pair of spaced side plates (12), a transverse bar or beam (14) and a hook or jaw (19).
The attachment head (23) is located between the side plates (12) with V-shaped slots (33) at one end of the head (23) engaged with the beam (14). A movable block (39) in the head (23) is moved by a hydraulic ram (43) into engagement with the hook or jaw (19) to lock the attachment head (23) to the operating tool (10).
